Question

My script extract span with it’s attributes. I want to replace span with attributes with something else. I am using following piece of code, maybe cause of special characters it doesn’t work.

    $tag=strtolower(str_replace("'<<span_id="ctl00_cphpagecontant_label6"><b>'","B",$tag));

Nesting quotes, ya’ need to escape ’em mate!

If you have a string wrapped in "" and would like this string to contain a literal " you will need some sort of method to say that "hey, I want this character here – but it’s not the end of the string", that’s where escaping comes in.

By prepending your character with a backslash \ you tell the PHP interpreter just that; this character is a part of the string, it’s not used to denote the end of it.

$tag=strtolower (
  str_replace ("'<<span_id=\"ctl00_cphpagecontant_label6\"><b>'","B",$tag)
);

Note: Does the string you’d like to replace start and end with '? Otherwise those characters should be removed from the string.
